Confused about how property taxes work when you buy or sell in Roseville? You are not alone. Between base rates, special assessments, and supplemental bills, it can feel like a moving target. This guide breaks down the essentials for Placer County so you know what to expect and what to do.

California basics that shape your bill

California’s system sets the foundation for every Roseville home. Under Proposition 13, the base tax rate is 1% of assessed value, and local voter-approved items layer additional charges such as school bonds or community facilities district assessments.

Without a change in ownership or new construction, assessed value generally cannot grow more than 2% per year, and a January 1 lien date dictates who appears on the secured roll for the July-through-June fiscal year.

If market values fall, counties may issue temporary Prop 8 adjustments, and you can always appeal if you believe the assessment is too high. Proposition 19 also changed taxable-value transfers and inheritance exclusions, so verify eligibility and timing before you close.

What your Roseville tax bill includes

The Placer County bill lists the assessed value, the baseline 1% rate, and any voter-approved additions or special assessments tied to your parcel. Many Roseville properties blend school bonds, parcel taxes, or CFD charges, so each bill is parcel specific.

Use the Assessor’s property search or parcel viewer, and the Treasurer-Tax Collector’s bill lookup to review assessed-value history and line-item charges. City and school district sites often maintain neutral lists of active bonds, helping you spot Mello-Roos or other assessments before making an offer.

Supplemental assessments after you buy or build

Supplemental tax triggers when ownership changes or new construction completes. It captures the assessed-value increase from that event and only covers the remainder of the current fiscal year.

How it works

Supplemental tax equals the local rate applied to the assessed-value increase, prorated for the fraction of the fiscal year remaining after the effective date.
The county sends a separate bill, often weeks or months after closing, in addition to the regular annual bill.

Who pays

Legally liability follows ownership dates, but the contract and escrow instructions determine payment. Sellers typically cover the period they owned the home, while buyers cover from closing forward.

If the supplemental bill has not arrived by closing, escrow may hold funds or specify payment terms, so ask for that detail in your closing documents.

Example: A $200,000 increase at a 1.20% combined rate with a March 1 effective date results in roughly an $800 supplemental bill for the rest of the fiscal year.

When bills are due and how proration works

California splits the secured bill into two installments each fiscal year, with specific due and delinquency dates posted by the county. Escrow often uses the most recent bill to calculate per-day amounts.

First confusing bills

Expect the regular secured bill on the normal schedule even if you just bought the home. A supplemental bill may arrive later and covers only the period after the change in ownership.

If you transferred an eligible base-year value under Proposition 19, the supplemental amount may be reduced or zero depending on your scenario.

The seller pays for the days they owned the home; the buyer covers days after closing.
If an installment has already been paid, the buyer usually credits the seller for the buyer’s share on the settlement statement.
If a supplemental assessment is expected but not yet billed, escrow may hold funds or clearly state who pays the future bill.
